This summer, more than usual, I ran a bit adrift when it came to blog-writing. There were many reasons, but the main reason was that it was so damned hot that I couldn’t bear to work in the garden and nothing would grow. July and August are always warm in New Mexico, but this year those months were beastly. A lot of my plants died because it was so hot that I couldn’t supply enough water to keep them alive. Or maybe I could have, but with the freezer already full to bursting it didn’t seem practical. I concentrated my efforts on watering the things that I like for fresh use.

But last week piles of pumpkins and squash started to show up outside the local grocery stores, and everything started to change. The wheel of the year has turned. Days are breezy and nights verge on chilly. The glorious scent of chiles roasting can be picked up near every grocer and market stand. The plants that survived the heat got a new lease on life. Cottonwoods started to turn gold.

Some of my mushroom bags, desiccated over the summer, imbibed water and started to fruit. They took me by surprise and I didn’t notice the new mushrooms until they were cracking at the outer edges. But they’re just fine for kitchen use. Sautéed or grilled or roasted, oyster mushrooms are pretty much the perfect all-around mushroom, mild and meaty and appealing to nearly everyone.

The tough stem bases that were trimmed off for cooking can be thoroughly dehydrated and ground into oyster flour. It’s perfect for thickening mushroom soup or sauces.

This year I made a mixed mushroom flavoring paste and froze it in ice cube trays to use for sauces and soups. I can’t give you an exact recipe but can convey the general idea, and no doubt you can improve on it. I used an assortment of five wild mushroom species from a foraging trip as well as the oysters, but you can use cultivated mushrooms. The last time I was in Whole Foods I saw seven varieties of cultivated mushrooms, and dried mushrooms are also available commercially, so anybody can get enough to try. My favorite source for bulk dried mushrooms is Oregon Mushrooms.

This formula can be endlessly adapted to any kind and any amount of edible mushrooms, although I don’t recommend lobster mushrooms because they don’t have much flavor to contribute.

Start with about three pounds of clean fresh mushrooms, at least a few different kinds, or about a pound of assorted dried mushrooms. I used oysters, hawkswing, agaricus, hen of the woods, lion’s mane, and cultivated shiitakes. If dried, soak them for an hour in enough hot water to cover them. Drain, strain any dirt out of the liquid with a fine strainer, and save the water. Pick over the mushrooms for any debris, then chop. This can be done in a food processor if you’re careful not to chop them to mush. Chop one large or two small onions and five cloves of garlic. Sauté the onions and garlic slowly in butter or good olive oil. When translucent and cooked but not browned, add the chopped mushrooms and sauté over medium heat until the mushrooms are somewhat cooked and exuding liquid.

Now add the mushroom soaking liquid if you used dried mushrooms, half a bottle of good red wine, a quarter cup of soy sauce or coconut aminos, six anchovy fillets, three or four good-sized sprigs of thyme, and any dried mushroom powder that you wish to add. I used some oyster powder and porcini powder, and also added about a cup of broken pieces of dried morels from a bag that I had finished up.

Cook the mixture over medium heat. Let it boil, because you want to concentrate down the fluid. When the fluid only just covers the mushrooms, remove the thyme stems and purée the mixture in the blender or food processor or right in the sauce pan with a stick blender.

Now you have a thick gloppy mixture looking something like this:

Cook over low heat until it gets really thick, stirring frequently to prevent burning. Add a quarter cup of best quality red wine vinegar and keep cooking. When the paste is dark and thick, taste it and add salt if needed. It should taste pretty intense. After all, it is a seasoning, not a food. When it is done to your satisfaction, smooth the paste into ice cube trays, cover, and freeze.

It will then lurk in your freezer, ready to add a deep taste of the forest to nearly anything where a mushroom flavor would be appropriate. After pan-grilling beef or game, toss a cube into the pan with some wine or broth and deglaze, boiling furiously, add a pat of butter, and boil a little more until it comes together as a pan gravy. Melt a cube into mushroom soup to enhance its flavor. Add a cube and some heavy cream to sautéed mushrooms that seem a little bland. Melt a cube, mix into an equal amount of soft butter, and use it as a finishing butter for meat or almost any kind of vegetable, or toss with hot pasta and some good Parmesan. Spread on hot buttered toast or stir into scrambled eggs.

Every time you use it, you’ll be reminded of the fascinating fifth kingdom that helps keep our planet alive.
